Description

  The present invention relates to an elevator apparatus including a rail bracket cover provided in an elevator hoistway.

  A car and a counterweight that lifts and lowers in the elevator hoistway in opposite directions are engaged with a pair of car guide rails and counterweight counterrails installed in the hoistway. By doing so, the up-and-down direction is guided. The guide rail for the car that guides the raising / lowering direction of the car and the guide rail for the balancing weight that guides the raising / lowering direction of the counterweight are fixed to a rail bracket provided on the hoistway wall or hoistway beam via a rail clip or the like. And are arranged over the range in which the car and the counterweight can be raised and lowered. The rail bracket that supports each of the guide rail for the car and the guide rail for the counterweight is configured by welding and fixing a plurality of support plates made of steel having a substantially L-shaped cross section. The guide rails are arranged at predetermined intervals based on the length and weight of each guide rail.

  In the conventional elevator apparatus in which each guide rail is supported by the rail bracket having such a configuration, for example, a car guide rail and a counterweight guide rail are respectively fixedly provided so as to protrude in the hoistway. It is fixed on both sides of the upper surface of the connecting beam that connects the standing columns fixed to the building frame, and this fixing bracket protrudes in the front horizontal direction and is longer than the horizontal width of the upper surface of the connecting beam. The rail fixing bracket is provided on the front side and the connecting portion with the counterweight guide rail is provided on both sides, and the rail fixing bracket is fixed on the both side fixing brackets in an adjustable manner in the horizontal direction. Have been disclosed (see Patent Document 1).

Japanese Utility Model Publication No. 4-42299

  Like the elevator apparatus described in Patent Document 1, the rail bracket that supports the guide rails of the car guide rail and the counterweight guide rail is constituted by a plurality of support plates made of steel or the like. This is because it is necessary to adjust the level of the support plate and adjust the centering of each guide rail when installing the rail bracket. After each adjustment, the support plate of the rail bracket is fixed by welding. Yes. For this reason, the rail bracket after the installation work has a complicated shape, and a large number of welded portions remain exposed. In addition, when adjusting the position of each support plate of the rail bracket, the accuracy of the reference surface only matters, and the end of the support plate after the placement of each support plate, especially the position adjustment However, the degree of protrusion from other support plates is not controlled, and the rail bracket as a whole has a cluttered structure.

  Since the rail bracket having such a configuration is normally disposed in the hoistway, it is not visible to users of the elevator, people near the landing, and the like. However, when a part of the car room wall and a part of the hoistway wall are made of a transparent body such as tempered glass as in the elevator apparatus for observation, a part of the hoistway wall is made of tempered glass or the like. In the case of an elevator apparatus that intentionally shows the configuration inside the hoistway to people near the landing, there has been a problem that the design inside the hoistway deteriorates.

  In addition, it is considered that the design of the interior of the hoistway is improved by pre-manufacturing part of the rail bracket in advance at the factory, etc., but the installation workability of the rail bracket and each guide rail deteriorates, There was a problem that the weight of steel and the production cost increased.

  This invention was made in order to solve the above-mentioned subject, and the objective is to provide the elevator apparatus which can improve the designability inside a hoistway by cheap and simple structure. .

  An elevator apparatus according to the present invention includes a lifting body that moves up and down in an elevator hoistway, a guide rail that stands in the hoistway and guides the lifting direction of the lifting body, and is provided in the hoistway to support the guide rail. A rail bracket and a rail bracket cover provided to cover the rail bracket.

  The present invention relates to a lifting body that lifts and lowers in an elevator hoistway, a guide rail that stands in the hoistway and guides the lifting direction of the lifting body, a rail bracket that is provided in the hoistway and supports the guide rail, Since the rail bracket cover is provided so as to cover the rail bracket, the design inside the hoistway can be improved with an inexpensive and simple configuration.

  In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.
